One year ago, your company purchased a machine used in manufacturing for $95,000.You have learned that a new machine is available that offers many advantages and that you can purchase it for$160,000 today. The CCA rate applicable to both machines is 20%; neither machine will have any long-term salvage value. You expect that the new machine will produce earnings before interest, taxes, depreciation, and amortization (EBITDA) of $55,000 per year for the next ten years. The current machine is expected to produce EBITDA of $25,000 per year. All other expenses of the two machines are identical. The market value today of the current machine is $50,000.Your company's tax rate is 38%, and the opportunity cost of capital for this type of equipment is 11%.
Should your company replace its year-old machine?

Q.no.1. (A) Some people seem to be more naturally skeptical whilst others find it easier to be trusting. These differences may be because of past experiences or personality traits. However, critical thinking is not about natural traits or personality; it is about a certain set of methods aimed at exploring evidence in a particular way. Elaborate with the help of an example.

You have been asked by the president of the Farr Construction Company to evaluate the proposed acquisition of a new earth mover. The mover’s basic price is $200,000, and it would cost another $30,000 to modify it for special use. Assume that the mover falls into the MACRS 5-year class, it would be sold after 4 years for $60,000, and it would require an increase in net operating working capital (spare parts inventory) of $10,000. The earth mover would have no effect on revenues, but it is expected to save the firm $50,000 per year in before-tax operating costs, mainly labor. The firm’s marginal federal-plus-state tax rate is 40 percent and the project’s cost of capital is 10 percent. Evaluate the project using the NPV rule and the IRR rule.

An electronics distributor sells a technology product with a very short lifecycle. The distributor orders the product from the manufacturer before observing demand and, due to the length of the supply chain, is unable to order more within the product life cycle. The manufacturer builds the product to order at a cost of $50 per unit and sells it to the distributor for $95 per unit. The distributor sells the product to its customers for $180 per unit. Demand for the product during its life cycle is expected to be normally distributed with a mean of 8,000 units and a standard deviation of 3,500. Any units left over at the end of life cannot be sold. In fact, due to hazardous materials used in the product, a fee of $5 per unit must be paid to properly dispose of any leftover units.
a. Using the single period (aka news vendor) model, what order quantity would maximize expected profit for the distributor? (Hint: think about what the price and cost would be from the distributor’s perspective.)
b. What order quantity would maximize expected profit for the supply chain (manufacturer plus distributor, i.e., the “globally optimal” order quantity)? (Hint: think about what the price and cost are for the overall supply chain.)
c. Suppose the manufacturer offers to reduce the price it charges the distributor to $55 in return for 15% of the distributor’s revenue from sales of the product. Explain why this type of revenue sharing contract is beneficial for the supply chain

The real risk-free rate (r*) is 2.8% and is expected to remain constant. Inflation is expected to be 7% per year for each of the next three years and 6% thereafter.
The maturity risk premium (MRP) is determined from the formula: 0.1(t – 1)%, where t is the security’s maturity. The liquidity premium (LP) on all Sacramone Products Co.’s bonds is 0.55%. The following table shows the current relationship between bond ratings and default risk premiums (DRP):
|
Rating |
Default Risk Premium |
|---|---|
| U.S. Treasury | — |
| AAA | 0.60% |
| AA | 0.80% |
| A | 1.05% |
| BBB | 1.45% |
Sacramone Products Co. issues 13-year, AA-rated bonds. What is the yield on one of these bonds? Disregard cross-product terms; that is, if averaging is required, use the arithmetic average.
11.58%
11.03%
10.38%
5.35%
Based on your understanding of the determinants of interest rates, if everything else remains the same, which of the following will be true?
The yield on U.S. Treasury securities always remains static.
Higher inflation expectations increase the nominal interest rate demanded by investors.

George Taylor, owner of a toy manufacturing company, is considering the addition of a new product line. Marketing research shows that gorilla action figures will be the next fad for the six-to ten-year-old age group. This new product line of gorilla-like action figures and their high-tech vehicles will be called Go-Rilla. George estimates that the most likely yearly incremental cash flow will be $26,000. There is some uncertainty about this value because George’s company has never before made a product similar to the Go-Rilla. He has estimated the potential cash flows for the new product line along with their associated probabilities of occurrence. His estimates follow
| Go-Rilla Project | ||
| Cash Flows | Probability of Occurrence | |
| $20,000 | 1% | |
| $22,000 | 12% | |
| $24,000 | 23% | |
| $26,000 | 28% | |
| $28,000 | 23% | |
| $30,000 | 12% | |
| $32,000 | 1% |
a. Calculate the standard deviation of the estimated cash flows.
b. Calculate the coefficient of variation.
c. If George’s other product lines have an average coefficient of variation of 12 percent, what can you say about the risk of the Go-Rilla Project relative to the average risk of the other product lines

In the body, hemoglobin (Hb) is the substance responsible for transporting oxygen (O2) to tissues. Hemoglobin binds oxygen to produce oxyhemoglobin (HbO2):
Hb + O2 ? HbO2
Carbon monoxide (CO) can also bind to hemoglobin to produce carboxyhemoglobin (HbCO):
Hb + CO ? HbCO
The equilibrium constant for Reaction 2 (KCO) is about 210 times larger than the equilibrium constant for Reaction 1 (KO2). Thus, carbon monoxide binds to hemoglobin much more efficiently than oxygen.
KCO/KO2 = 210
a. Write a balanced equation for the displacement of oxygen from HbO2 by CO to produce HbCO. Write the equilibrium constant expression for your overall reaction.
b. Write an expression that relates the equilibrium constant for the overall reaction (i.e., from Question 1) to the equilibrium constants KCO and KO2.
c. Use your balanced equation from part (a) and your knowledge of equilibrium constants to explain why patients who are experiencing CO poisoning are generally given pure oxygen as a remedy.
